RADIATOR.

T o all t may concern.

Be it known that-I, JOSEPH A. HRoMADKo, a citizen of the United States, residing at New I-Iaven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Radiators, of which the following is a full, clear,

and exact specification.

This invention relates to radiators `for motor vehicles, and has for its object to simplify the construction of such radiators, reduce the weight thereof, and improve the circulation and radiation of heat therein.

It is the aim of the invention to produce a radiator of thin plates which may be stamped or pressed out from the same pat-- tern and fastened together in oppositely facing pairs to form sections any number of which may be assembled to construct the desired size of radiator. The invention also contemplates the provision of horizontal ,water circulating passages between the vertical water passages across the air passages, so that the radiating efficiency of the radi- 'ator will be increased,v by the horizontal circulation of the water from side .to side of the radiator as well as vertically from bottom to top thereof. Other objects will ap ear as the description proceeds.

hev invention willbe first hereinafter described in connection with the accompanying drawings, which constitute part of thisA specication, and' then more specifically the same dened in the claims at the end of the description. y In the accompanying drawings, wherein similar reference characters are used to designate corresponding parts throughout the 'several views Figure 1 is a front elevation of a radiator constructed substantially in accordance with this invention.

-. Fig. 7 is a section on the line VII-VII of Fig. 2.

In Figs. 1, 2 and 3, the frame of the radiator is indicated at 1 with the .upper and lower headers 2 and 3. The body of the radiator is composed of a plurality of sec. tions 4 each comprising two similarly formed and oppositely facing plates 5 and y6 having overlapping flanges 7 at their rectly into the air passages.

At the front .and rear edges of the plates 5 and 6 of each section there'are formed outwardl turned flanges 11 and 12 which are joine 13, so as to form the vertical water passages 14 between each pair of adjacent sections 4.

he protuberances 9 are fiush with said flanges 11 and 12 on the respective plates 5 and 6, and abut against one another to'properly space the sections apart.,l

As illustrated i Fig. 6, horizontal transverse water passages 1-5 may be formed between the protuberances 84 by interlocking the punched out ends of said protuberances as at 16, one having an extended neck portion extending into and suitably secured to rovides for the other. This construction rom side to side of the radiator as well as from bottom to top'.

together by solder or the like,-asat` Having thus described my invention, what I claim as new and desire to secure by Letters Patentvof the United States is 1. Avx radiator comprising sections each consisting of duplicate opposed .plates arranged parallel to each other and connected together at the` upper and lower edges to form air passages between them, said plates having protuberances on both faces thereof pressed out from the sheets of which the plates are composed, the inwardly extending protuberanceshaving their ends contacting with one another on the opposed 'plates comprising the same section and ormin spacing means for said plates and also additional water circulating spaces, said plates having outwardly turned flanges on their front and rear edges joined to similar flanges on the adj acent sections to form the water circulating passages of the radiator, the outwardly extendin protuberances on the plates of each sectlon being of the same extent as'said j flanges and having their ends abutting against those ofl the adjacent section for spacing` the sectionsy apart.

2. A radiator comprising sections each `consisting ,of duplicate opposed plates arranged parallel to each other and connected 'together at their upper and lower edges to posed plates of each sectionapart and form additional water circulating spaces, said plates having outwardly turned flanges on their front and rearedges joined to similar anges on the adjacent sections to form the water `circulating'passages ofthe radiator;

'the outwardly extending protuberances on the plates of each section being flush with ing the sections apart.

A radiator comprising sections each consisting of duplicate'o posed plates arranged parallel toeach ot er and connected together at their upper and lower edges to i form air passages between them, said plates having protuberances on both faces thereof pressed out from the sheets of which the plates are composed, the inwardly extending communicating with the water circulating passages between the adjacent sections, thus providing for the horizontal as well as the vertical `circulation of the water in the radiator and additional water circulating` spaces in said protuberances which extend inwardly of the individual sections, said plates being connected along their front and rear edges to form the water' circulating passages, and the outwardly extending protuberances on the plates of each section having their ends abutting against the corresponding ends of the protuberances of the adjacent sections for spacing said sections apart. v l

I 4. A radiator comprising sections each consisting of spaced `plates arranged parallel to each otherand connected together at their upper and lower edges to form air passages between them, said plates having outwardly turned flanges vat their front and rear-edges joined to similar flanges on the adjacent sections' to form the water circulating passages of the radiator, and outwardly extending protuberances pressed fromV said plates of each section and having theirouter ends flush withthe lilanges on the same plates, said protuberances having their ends abutting `against the ends of thosel on the adjacent sectionsfor spacing the sections apart.
